Ultimax Pro Drive Belt....vintage snowmobile
So far the Ultimax Pro belt has held up great, we race vintage snowmobiles and would blow the factory belts. Then I found out about Carlisle Ultimax Pro Belts and we used it for a race, we blew out our secondary clutch but did not hurt the belt. We have two more races set up for this year and I am sure the belt will be great!!

Ultimax is Ultamit
This belt has some of the best features that you can find in a belt. The ribs on both sides help to dissapate heat while still making it bendable. Should get many trouble free miles out of this baby.
